These headphones provide a very good balance of performance, cost and comfort. The sound quality is very good, the comfort for long aeroplane flights (the main use) is good and the cost of the SE version, especially when bought 'refurbished' is also very competitive. Don't intend to use these for making phone calls, so can't comment on that aspect of performance. Worth noting that they come with a soft bag, so its worth considering buying a Geekria hard case to give added protection for travelling (~£16 on Amazon).
Pros - Lightweight and near total blackout of external noises leaving a total immersive sound experiance .
cons - Had some difficulty trying to pair up with my samsung smart tv ( bose own site suggestions just would not work ) but after scanning through you tube i was able to sort it easily .
I find the controls switches a bit awkward owing to their location on the headset .
